How Can Laser Technology Improve Material Processing?

Scroll to Section:

Lasers typically produce a Gaussian beam where intensity is greatest in the center and tails off at the edges. In this video, ULRIKE FUCHS explains how a laser beam profile can be transformed into something more effective for material processing. Drawing on insights from phase shifting microscopy, Fuchs shows how a phase plate can be used to change the phase distribution of an incoming Gaussian beam before it is focused. Along with making existing processes faster, more efficient and more precise, Fuchs’s work reveals potential for exciting new applications for laser technology going forward.
